We decided to test thermal energy harvesting usability in reality. As we mentioned in other articles Peltier element cannot generate high power, but we can store this power in some time interval and then use it. We already described functionality of Peltier element (aka. Thermo electric cooler - TEC) and ECT 310 boost converter and here we will measure their performance.
Thermoelectric coolers (TEC) operate by the Peltier effect (which also goes by the more general name thermoelectric effect). The device has two sides, and when DC current flows through the device, it brings heat from one side to the other, so that one side gets cooler while the other gets hotter.
It is time for fun. If you accepted that using Android phone to control hardware is fun:) Android become very popular and if you into microcontrollers it is pity not to use that knowledge for making cool applications. If you experienced with microcontrollers it is useful to expend your knowledge with any object oriented language. That can be useful for future job opportunities. For Android you need to know Java programming and usage of Eclipse IDE for Java developers. Maybe sounds hard, but today there are a lot of free online courses about Android and plenty of examples and complete projects.
